When shifting between adjacent gears, different operating procedures are required. Regardless of the gear shifting method, the rotational angular velocity of the gear ring to be engaged and the engaging sleeve, or the linear velocity at the meshing point of the gear to be engaged, must remain consistent.
However, the underlying principles of speed analysis are similar. Gear shifting operations in a transmission, especially downshifts from high to low gears, are relatively complex and can easily cause impact between gear teeth or spline teeth. To simplify operation and avoid tooth impact, synchronizers can be installed in the shifting mechanism. Inertia synchronizers achieve synchronization through friction and are equipped with a dedicated mechanism to ensure that the engaging sleeve does not contact the spline gear ring to be engaged before synchronization is achieved, thereby preventing tooth impact.
